Abstract

The invention relates to the technical field of SCR flue gas denitration, particularly to a nitrogen and oxygen generation device and a catalyst reaction performance detection device of a thermal power plant. The nitrogen and oxygen generation device is disclosed, wherein when a flow regulating valve is turned off, a molecular sieve in an adsorption column separates oxygen to obtain pure nitrogen;when the flow regulating valve is turned on, the concentrations of nitrogen and oxygen can be adjusted according to the opening degree of the flow regulating valve to obtain required nitrogen and oxygen concentrations. The generation device can directly replace purchased nitrogen and oxygen, reducing the test cost of a catalyst activity test, and reducing a step of mixing pure nitrogen and pure oxygen, and making operation convenient and fast.

Description

technical field [0001] The invention relates to the technical field of SCR flue gas denitrification, in particular to a nitrogen and oxygen generator and a thermal power plant catalyst reaction performance detection device. Background technique [0002] At present, an important technical means for thermal power plants to achieve ultra-low NOx emissions is the use of selective catalytic reduction (SCR) denitrification technology. SCR flue gas denitrification catalyst in catalytic NH 3 Reduce NO X When, the catalyst will also lead to a series of side reactions, including making SO 2 Oxidation to SO 3 , Hg 0 Oxidized to Hg 2+ . Catalyst is the core of SCR flue gas denitrification technology, and the performance of catalyst is the main factor affecting the efficiency of SCR denitrification. Therefore, before the denitrification catalyst is applied, it is necessary to accurately test the reaction performance of the SCR catalyst, including the denitrification efficiency of ...
